Re: [PATCH 2/3] mm: page table check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It seems after updating to linux-next-20211125, my system is crashing frequently due to "kernel BUG at mm/page_table_check.c:101".

linux-next-20211124 does not have the issue.

A bug was also reported on
https://bugzilla.opensuse.org/show_bug.cgi?id=1193125

journactl output before sysrq reboot:
